My family is long history of GM workers. They are the same. My family told me a long time ago the only differance is GMC keeps there value a little better because they have the luxury bells and whistles. They put comfier springs in the seats, better plastic on the heating vents, just little ticks and tocks.
Technically, just the name. They are both made by General Motors. The only difference is in the cosmetic appearance. Hope this helps ya.
My grand dad used to tell me that chevy was a GMC with about 100 more welds! hehe
wow two girls knowing that GMC and Chevrolet are the same.... I'm in love! jk
CHEVY IS BETTER!! THATS WHAT!
